Use class initializers where possible and pass required values to the
constructor instead of initializing them afterwards. Also the use of
QQmlRefPointer allows for the elimination of manual reference counting.
Re-ordering the members shrinks the size on x86-64 from 56 to 48 bytes
per instance.

Storing QObject pointers in a dynamic role model man end up crashing the
application once those objects get deleted.
As it looks impossible to make QVariant::fromValue<QObject*>(...) track
the life cycle in a binary compatible way, this patch fixes the crashes
by tracking with a QPointer at the level of QVariant storage. That's the
QQmlOpenMetaObject in the case of the dynamic role model. In principle a
similar approach is already in place for storage of QML declared
properties - this patch mirrors the approach.
Test cases provided by Ben Lau <xbenlau@gmail.com> and Chris Adams
<chris.adams@jollamobile.com>.

Use a vector instead of a list for a more compact storage - random
access is a more frequent operation than appending/removal. Also use
a struct instead of a QPair for increased readability of the code and
encapsulate read and write operations.
Clean up the internal API to avoid unnecessary mutable property
extraction. This also helps to ensure that in all cases but intended
mutation we end up using the property getter that returns a QVariant by
value, something that will allow returning a null variant when QObject
tracking gets fixed in the next patch.

From now on we prefer nullptr instead of 0 to clarify cases where
we are assigning or testing a pointer rather than a numeric zero.
Also, replaced cases where 0 was passed as Qt::KeyboardModifiers
with Qt::NoModifier (clang-tidy replaced them with nullptr, which
waas wrong, so it was just as well to make the tests more readable
rather than to revert those lines).

When called, the function would return a full-fledged QObject that maps the
list element addressed. It would contain a _copy_ of all values in the list
item and it would create a new meta-object for each list element.
This function exists for the JavaScript API, and therefore we now return a much
more lightweight object. For compatbility reasons it still has to be a QObject,
but the meta-object of it is created on-demand, i.e. only when accessing
properties from the C++ side or when connecting to the changed signal of a
property. Otherwise the JavaScript wrapper will return the live values from the
model without copying them.

The QQmlEngine has two containers for property caches, one for QML types and
one for all-purpose meta-objects. The latter is rather useful and now being
moved to QJSEngine to be available there.

properties
Commit 84627464eb11ca1149d46946b12e3c82eb54a8bf introduced a performance
regression of falling back to reading the QMetaObject, when the lookup for a
property in QML failed, after we've tried in the property cache. This is very
very expensive to do and was only due to QQmlPropertyMap not correctly
invalidating the property cache.
Instead remove the property cache from the property map's QObject and on the
lookup side rely on the property cache being correct in the result (positive or
negative).
